Hammond Power Solutions SK3A0030PK4K is a three-phase general duty transformer engineered for industrial and commercial power distribution, providing reliable voltage transformation and isolation. It operates with a 600V delta primary and 480Y/277V wye secondary configuration, delivering 30 kVA at 60Hz with ±2.5% and ±5% voltage tap adjustments. Housed in a Type 3R / IP24 rated enclosure with an ANSI 61 grey finish, this unit measures 28.75 inches high by 25.75 inches wide by 23.8 inches deep and weighs 325 lb, utilizing a 150°C temperature rise with 220°C insulation class materials. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets seismic standards including OSHPD and IBC 2018 with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring robust power transformation with mechanical lug secondary terminations and a 45 dBA sound level.
